The dimensions of this cylinder are height (h) = 2 and radius (r) = 1. What is the volume?
| 2π | |
| 216π | |
| 243π | |
| 108π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(12 x 2)
v = 2π
Breaking apart a quadratic expression into a pair of binomials is called:
normalizing |
|
deconstructing |
|
squaring |
|
factoring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
The formula for volume of a cube in terms of height (h), length (l), and width (w) is which of the following?
h x l x w |
|
2lw x 2wh + 2lh |
|
lw x wh + lh |
|
h2 x l2 x w2 |
A cube is a rectangular solid box with a height (h), length (l), and width (w). The volume is h x l x w and the surface area is 2lw x 2wh + 2lh.
The formula for the area of a circle is which of the following?
c = π r2 |
|
c = π d2 |
|
c = π d |
|
c = π r |
The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)2 : a = π r2.
This diagram represents two parallel lines with a transversal. If d° = 154, what is the value of a°?
| 26 | |
| 29 | |
| 143 | |
| 31 |
For parallel lines with a transversal, the following relationships apply:
Applying these relationships starting with d° = 154, the value of a° is 26.
